Their 20+ years of marketing experience confirmed the reliability and value of our solutions, giving them confidence in adopting our chambers for material testing.
Reliable testing starts with adhering to internationally recognized standards. The following standards are critical for Xenon light fastness testing:
ISO 105-B02 (Textiles): Specifies procedures for testing the color fastness of textiles using Xenon arc lamps. It defines exposure times, light intensity, and humidity conditions to produce reproducible results for fabrics, dyes, and printed textiles.
ASTM G155 (Plastics and Coatings): Provides guidance for operating Xenon arc light apparatus for non-metallic materials, including black panel temperature, light spectrum, and moisture cycling. It is widely used for plastics, paints, and coatings to predict outdoor durability.
EN ISO 4892-2 (Plastics): European standard for plastics, outlining Xenon arc lamp exposure for accelerated aging. It emphasizes realistic simulation of natural sunlight and environmental conditions.
ISO 2836 / ISO 105-B (Printing and Packaging): For inks, packaging films, and printed substrates, ensuring color durability and fading resistance under standardized light exposure.
By following these standards, manufacturers can obtain scientifically accurate and reproducible results, enabling better material selection, formulation optimization, and product design.
